Abstract
Disclosed herein are an access control system and an access control method using the same. The access control method in which a door operating device determines whether to open a door on the basis of an authentication token acquired from a user terminal without intervention of an authentication server includes obtaining the authentication token from the user terminal; determining whether the user have authorization for accessing the door based on a authentication information included in the authentication token; controlling the door to be opened in case of determined that the user have authorization for accessing the door.
Claims15
An access control method performed by a server, the access control method comprising:
- receiving a first information from a target device located in a target area;
- wherein the first information is pre-stored in the target device,
- wherein the first information includes at least one of identifier of a first user and identifier of a first user terminal for the first user,
- receiving a second information related to a second user terminal for a second user;
- wherein the second information includes location information used for determining the location of the second user terminal and at least one of identifier of the second user and identifier of the second user terminal, and
- determining the first user terminal is matched to the second user terminal when the at least one of the identifier of the first user and the identifier of the first user terminal corresponds to the at least one of the identifier of the second user and the identifier of the second user terminal;
- determining the location of the second user terminal based on the location information included in the second information;
- wherein the location of the second user terminal is determined such that it is established whether the second user terminal is located inside the target area or the second user terminal is located outside of the target area,
- determining the location of the first user terminal as the location of the second user terminal when the first user terminal is matched to the second user terminal;
- and
- transmitting a message for allowing the use of the target device to the target device when it is determined that the location of the first user terminal is inside the target area;
- wherein the location information indicates whether a first target door located in the target area for entering the target area is opened;
- and
- wherein the first target door is opened by a request from the second user terminal and authentication by the server when the second user terminal is located in the outside of the target area.

An apparatus, comprising:
- a control unit configured to:
- receive, a first information from a target device located in a target area;
- wherein the first information is pre-stored in the target device,
- wherein the first information includes at least one of identifier of a first user and identifier of a first user terminal for the first user,
- receive, a second information related to a second user terminal for a second user;
- wherein the second information includes location information used for determining the location of the second user terminal and at least one of identifier of the second user and identifier of the second user terminal, and
- determine, the first user terminal is matched to the second user terminal when the at least one of the identifier of the first user and the identifier of the first user terminal corresponds to the at least one of the identifier of the second user and the identifier of the second user terminal;
- determine, the location of the second user terminal based on the location information included in the second information;
- wherein the location of the second user terminal is determined such that it is established whether the second user terminal is located inside the target area or the second user terminal is located outside of the target area,
- determine, the location of the first user terminal as the location of the second user terminal when the first user terminal is matched to the second user terminal;
- and
- transmit, a message for allowing the use of the target device to the target device when it is determined that the location of the first user terminal is inside the target area,
- wherein the location information indicates whether a first target door located in the target area for entering the target area is opened;
- and
- wherein the first target door is opened by a request from the second user terminal and authentication by the apparatus when the second user terminal is located in the outside of the target area.
